Invites to the latest Closed Beta haven't necessarily gone out yet--the quote is around January 28th, meaning it could be as late as the 30th, depending on how you read the word "around" :P . However, if you really don't get into the Closed Beta, your spec that you submitted is automatically registered for the Open Beta, which you are guaranteed to get into.

Basically, wait a few more days for the announcement that CB invites have gone out. If you don't get one, wait until the end of February and you will be in the Open Beta!

that just answer my question, thx
i'm in the same place, signed before the open beta had been told, but not got the mail for close beta yet
